There's this adage about consuming whatever newspaper reporting, everything seems fine and dandy, until one day they report on something in your field. Say, chemistry, and you're a chemist, and... it's all wrong. Even the ba

Sure. But even restoring from backup means a cost is being inflicted, and not a small one.

Is that an offhanded joke on the terminology or do you actually mean something? I can't tell.

Fair, I'm in fact not 100% sure it's a joke. But there's a smiley, that's pushing me to 90%.

I think you missed the joke/sarcasm there.

Or help distributions do the manual process of packaging - which involves at least rudimentary security checks - so they can ship newer versions faster. And then use distro packages. (I'm not accepting distro fragmentation as counter

I noted this in https://news.ycombinator.com/item?id=48079649 I also pointed out in that comment that USB-C debug accessory detection does not support orientation detection - and neither does the Google adapter you linked (

It's not a byte sequence, it's a BREAK == pulling the line low for longer than a byte, i.e. invalid serial framing on the stop bit.

This seems to be assuming that he's the only person on the jet? Otherwise you'd need to divide by the number of people being transported. (I don't think the jet can carry 48 people, which is what you'd need to break even

Indeed… a fact making me really sad about BLE :(. The Nordic profile might become widespread enough to become de-facto standard, but AFAIK isn't quite widespread enough yet, i.e. people are still homebrewing almost the same thing(?)

Yes, yes :). I was really joking with the 7 pins. It would be amazing though to make it a hermaphroditic 4 or 6pin connector. With a pinout like this: GND TX [VrefTX VrefRX] RX GND So it always plugs at a 180° rotation, connecting

In my experience with... it's maybe 20? ... embedded boards, junk during boot breaks the boot flow for about half of them. And attaching quickly after target powerup is very often the crux of the exercise, to get to the bootloader fas

Thing is, for a serial TTL connector to become ubiquitous, it needs to cover at least something like 99% of scenarios. Or maybe 95%. 3.5mm TRS ain't that , and thus just increases general diversity in connectors.

Is there a standard for TTL-serial pinout on those? I'm not aware of one, only for SWD…
319.
by eqvinox 5mo ago
At that point it's not a debug connector anymore. Note there's a pseudo-standard for V.24/RS232 on RJ45 already, and nobody uses it for debug connectors since (a) you'd need a RS232 transceiver and (b) RJ45 connectors ar

FUSB307B is amazing for this, it has a hardware DBG output pin indicating that a USB-C debug accessory mode connection has been made. Perfect for connecting a mux and putting SWD & serial on some USB-C pins. Too bad there's no sta

Random in the time sense. You'll get junk on your serial line, depending on the scenario that can matter a lot.

And where do I put Vref, RTS, CTS, and plug detect? That's 7 pins ;) </jk> Less of a joke though: those aren't polarized, how do you not accidentally 180° them? Are they magnetically polarized or what? [ed.: I didn&#x27

That really sucks for hotplugging since TRS connectors sliding in basically make random connections before seating properly. Granted, you shouldn't hotplug TTL serial, but everyone™ does it anyway. (In some situations you're even

That's not a revive though, revive (at least to me) implies it's dead.

The only things with a chance at succeeding in this space are putting USB-serial directly on the board + USB-C, or alternatively bluetooth classic RFCOMM profile. (The latter is a very long shot.) Apart from that, this doesn't even to

+1, a project presenting at FOSDEM certainly does not need a "revive".

Federal law enforcement in your DC isn't something you'd call a "compliance" issue, that's not what that term means. Yes it's various derivatives of the English word "comply", but this is a field of

Short-lived = 6 days. Even if you reissue after 2 or 3 days, that's… not a lot of breathing room.

I don't have enough hubris to assume I know things the people on LKML (or actually netdev in this case) don't. If anything, I might unicast a mail to Steffen.
